# Migrators

## XPump

[Implementation](https://github.com/interest-protocol/memez-gg/blob/main/migrators/xpump/sources/xpump.move#L181)

The Blast.fun migrator creates a new pool on Bluefin and adds liquidity. The liquidity position is saved and can later be used by the Admin or developer to claim fees based on the configuration.

```rust
public fun migrate_to_new_pool_v3<Meme, Quote, CoinTypeFee>(
    config: &mut XPumpConfig,
    bluefin_config: &mut GlobalConfig,
    clock: &Clock,
    ipx_treasury: &IPXTreasuryStandard,
    meme_metadata: &CoinMetadata<Meme>,
    quote_metadata: &CoinMetadata<Quote>,
    migrator: MemezMigrator<Meme, Quote>,
    fee: Coin<CoinTypeFee>,
    ctx: &mut TxContext,
): Coin<Quote>
```

The Bluefin pool is initiated with the following parameters:

* <mark style="color:yellow;">**Tick Spacing:**</mark> 200.
* <mark style="color:yellow;">**Initialized Price:**</mark> Dynamically calculated based on the quote and meme coin balances to be added.
* <mark style="color:yellow;">**Tick Lower Index:**</mark> 4294523696
* <mark style="color:yellow;">**Tick Upper Index**</mark>: 443600
  * This is to ensure full range liquidity
